Myelination, the process by which glial cells ensheath the axons of neurons in layers of myelin, ensures the rapid conduction of electrical impulses in the nervous system. The formation of myelin sheaths is one of the most spectacular examples of cell-cell interaction and coordination in nature.
Saltatory conduction is a type of nerve impulse that occurs when an electric signal jumps from one bare segment of fiber to the next. Action potentials are perhaps best understood as electrical impulses that act as signals to and from neurons and muscle cells.hese are called the â nodes of Ranvier .â Saltatory conduction happens when signals âhopâ from myelin sheath to myelin sheath, essentially skimming over the top of the axon.
